Pre-gapped breaker point assembly

Abstract

A pre-gapped breaker point assembly for a distributor of an internal combustion engine, the assembly having spacing blocks which are configured to pre-position the breaker contact points of the assembly at a correct spatial separation during placement of the breaker point assembly in the distributor of an internal combustion engine. The spacing blocks substantially eliminate subsequent adjustment of the contact points by suitably orienting the breaker point assembly with respect to the cam in the distributor.

What is claimed and desired to be secured by United States letters patent is: 
     
       1. A pre-gapped breaker point assembly for a distributor of an ignition system of an internal combustion engine, the assembly being adapted to be adjustably mounted on a moveable mounting plate in said distributor, the breaker point assembly being secured in proximity to a cam of said distributor, the assembly having a cam follower resiliently urged into contact with said cam and having an arm attached thereto, the arm terminating in a first breaker contact point, the cam follower being operable between said cam and said moveable arm so as to intermittently separate said first contact point from second contact point coincident with a high point on said cam, the first contact point being electrically isolated from the breaker point framework and the second contact point being in electrical contact with said breaker point framework; the improvement comprising: means for independently mounting at least two separately mountable spacing blocks on said breaker point assembly, each of said mounting means comprising a flange on the breaker point assembly and upon which flanges said spacing blocks are removeably mounted, said spacing blocks comprising a first and a second spacing block, each spacing block comprising at least one abutment surface adapted to be placed in juxtaposition against at least one high point on said cam to thereby selectively achieve a suitable predetermined position of said breaker point assembly with respect to the breaker plate and in coincident with the cam follower at a third high point on said cam and thereby establish a predetermined maximum separation of said first and said second contact points; and   a substitute spacing block for the first spacing block and mountable upon the flange to change the relative position of the breaker point assembly with respect to the cam without affecting the position of the second spacing block on the breaker point assembly.   
     
     
       2. The improvement of claim 1 wherein said means for independently mounting said spacing blocks comprise at least two flanges on said breaker point assembly, each flange dimensionally configurated to accommodate removeably mounting said spacing blocks upon said breaker point assembly so as to selectively permit independent removal of said spacer blocks after the breaker point assembly has been secured to said mounting plate.
